Sergey Borachev: I think that, after reading all the previews, this camera will be the most successful of all mirrorless in 2012, provided there are no surprises in the QC. It should get a couple of Camera of The Year Awards. Any flaws seem very minor and cannot distract from the fact that this camera gets all the important things right for a small capable camera.

I wish Olympus will start releasing black versions and/or silver (same colour as the silver on the E-M5) versions of their lenses, replacing those other non-standard "silver" colours, since this is their flagship camera and it look fantastic (except for the mismatched silver colours and silver lenses do not look so good on all black cameras).

I think this will be the start of a distinct line of cameras that Olympus and its owners will be so proud of, just like the OM-1, 2, etc.

I hope this will save Olympus and free it from the beancounters style of management and it will continue to produce OM-D cameras that excites. Thank you.

I'd guess the loss is in the highly competitive compact camera section, rather than with the EVIL cameras where people are willing to pay twice as much compared to a standard 4/3rds lens of similar size. Maybe there's also a loss counted on the standard 4/3 inventory which is probably hard to sell now without a big discount.

If the camera's weight and depth is sufficiently reduced, a 1" sensor could be acceptable to me, but I'm not sure that's the case here. Also, I'm not so keen on paying "full price" for the optics for a "baby" system. I also want the controls of an enthusiast camera and plenty of customisation. Good that they have an EVF at least.

Rob Klein: I am not sure who or what Nikon wishes to better with this offering, but the entire concept does nothing for me. I am now curious as to whether Canon will come forth with a m4/3 system or will be looking to compete with the Fuji X100 and put a digital gut into one of its tried and true rangefinders from the last century with interchangeable lenses like Leica, but for a Canon price. It is clear that most of the posters here are not just shooting with point and shoots and this system seems to be an expensive version of that with some frosting that makes one want to put your finger in and taste, but not necessarily then ask for a piece.

Hmmm Harrold66, Panasonic, Samsung, Sony and Nikon make their sensors too. Only Oly and Pentax don't.
